Fast, Reliable General Contractor Across Oak Hills
If you’re planning a home addition, garage conversion, or ADU on your Oak Hills property, you need a general contractor who understands San Bernardino County permitting, septic and well setbacks, and high-desert wind loads. That’s who we are. San Bruno Construction has managed full-scope residential projects across the 92344 corridor, from interior remodels to detached ADUs, and we coordinate every trade, material order, and county inspection so you don’t have to. Call Noel and our team at (866) 472-1908 to talk through your project. Estimates are free, and we scope the county-level items before we quote, not after.
Why San Bruno Construction Is Oak Hills’s Preferred General Contractor Company
Oak Hills homeowners keep calling us for one reason: we plan for the things that derail projects out here. A tract-home contractor from down the hill doesn’t know that a room addition off Ranchero Road may need a percolation test and engineered septic design before San Bernardino County will even look at your permit application. We do. That knowledge shows up in our quotes, our timelines, and our final walkthroughs. We’ve built a local reputation around accurate scoping and honest scheduling on multi-acre parcels where every project has its own well, leach field, and wind exposure to plan around.
We’re the General Contractor team homeowners call when they want one accountable point of contact across every phase: site work, foundation, framing, roofing, plumbing coordination, finishes, and final county sign-off. Whether you’re remodeling a kitchen inside an existing Oak Hills home or building a detached shop with living space, you’re not managing five subcontractors. Noel coordinates the trades, the material deliveries, and the inspections. When you call, you speak with someone who has walked your kind of job before.
Styles & brands we work with
Licensed General Contractor in Oak Hills
A Licensed General Contractor in Oak Hills manages the entire build: permits, subcontractors, materials, inspections, and the schedule. On a high-desert lot, that role matters more than it does in a city with municipal water and sewer, because the permit path runs through San Bernardino County, not a city building department. We handle that. If you’re adding a bedroom, converting a garage, or putting up a new outbuilding, the county will ask about your septic system, your well, your grading plan, and your wind tie-down schedule before approving anything. We prepare those answers before we quote, so the price you see reflects what the county will actually require.
County Permitting and Septic Coordination
Most Oak Hills properties sit outside city limits, which means San Bernardino County plan check, not city plan check. Septic and well setbacks drive a lot of decisions: the leach field has to stay clear of new foundations, the well head needs proper separation from habitable additions, and any grading that changes drainage across a parcel line needs review. We handle these conversations on your behalf.
Outbuildings, Shops, and Detached Structures
Custom homes and manufactured homes on multi-acre parcels usually mean detached garages, workshops, and horse facilities. Adding another structure, or converting an existing one, involves structural review, wind-load calcs, and often a separate septic or electrical scope. We’ve done it enough times on Oak Hills lots to know what the county will flag before they flag it.
Residential General Contractor in Oak Hills
A Residential General Contractor in Oak Hills handles everything from a kitchen remodel inside the house to a full site-built addition off the back. We coordinate the licensed trades (electrical, plumbing, HVAC) and manage the materials, so you get one schedule and one contract. Kitchen remodels here run $14,000 to $45,000, bathroom remodels $9,000 to $28,000, and a home addition typically lands between $45,000 and $130,000 depending on size, site access, and whether the septic system can absorb the added load. Those are Oak Hills numbers, not Orange County numbers.
Interior Remodels with Real Material Choices
For kitchens, we bring cabinetry lines like KraftMaid and Wellborn, countertops from Cambria, Silestone, and Caesarstone, and plumbing fixtures from Kohler, Moen, Grohe, and Toto. You choose from real brands with real performance records, not whatever the contractor has sitting in a warehouse. For bathrooms, the same applies: you pick the vanity, shower system, and tile from vetted product lines, and we handle installation and coordination.
Site-Built Additions and Garage Conversions
Garage conversions in Oak Hills run $30,000 to $80,000. A full habitable addition starts around $45,000 and can reach $130,000 on a custom build with upgraded finishes and site challenges. The wild card is always the septic system: a converted garage adding a bedroom and bathroom may trigger a leach field upgrade the original quote didn’t include. We check that first. It’s the difference between a price that holds and one that balloons mid-project.
Trusted Brands We Service in Oak Hills
We maintain working relationships across over 50 established product brands, so Oak Hills homeowners aren’t limited to a single source for windows, doors, roofing, and exterior materials. Need impact-rated windows for a west-facing exposure off Mesquite Street? We can source from CWS or ES Windows. Re-siding a shop or outbuilding? James Hardie and Therma-Tru are in our lineup. We keep lead times realistic for 92344 deliveries, and because we order materials early in the schedule, you’re not waiting on a backordered door while the framing crew stands idle. One contractor, every phase, and materials chosen from brands engineered to last in this climate.

AfterCommon General Contractor Problems We See in Oak Hills Homes
- Skipped perc tests and septic reviews. Homeowners get a quote for an addition, then the county requires a $5,000 to $15,000 septic upgrade. We won’t quote a habitable addition in Oak Hills without checking the septic envelope first. That’s the information-gain step that keeps your number honest.
- Wind exposure underestimated. Lots on the open desert edge, especially east of the 15, see wind loads that down-the-hill tie-down schedules fail. We spec shear-wall and hold-down details to San Bernardino County’s high-wind requirements before we pull permits, not after the first plan-check correction.
- Material haul and equipment access ignored. Unpaved, sloped driveways off Bear Valley Road or Coyote Trail can turn a standard dumpster delivery into a truck that won’t make the turn. We scout access early and price hauling accurately, so the draw schedule doesn’t stall.
- Owner-builder projects without a GC safety net. Many Oak Hills homeowners start as owner-builders, then hit the county’s plan-check wall. We step in as the licensed coordinator, take over permit management and trade scheduling, and get the project moving again. You keep the vision; we carry the accountability.
Pricing for General Contractor in Oak Hills, CA
Here’s what we’re seeing across Oak Hills right now, for planning purposes. A detached ADU typically runs $90,000 to $220,000. A site-built home addition lands between $45,000 and $130,000. A garage conversion runs $30,000 to $80,000. These ranges include the county-driven scope items we’ve talked about: septic review, well setbacks, wind tie-downs, and grading. If a lot has a failing leach field or a well head too close to the proposed structure, the number moves toward the top of the range or beyond. That’s not a surprise cost when we scope it up front.

FAQs About General Contractor in Oak Hills
Yes, in most cases. Any habitable addition that adds bedrooms or plumbing fixtures triggers San Bernardino County to verify the existing septic system’s capacity, and a percolation test with an engineered septic design is the standard first step. We arrange the perc test, the civil engineer, and the county submittal as part of our pre-construction scope. Call (866) 472-1908 and we’ll check your parcel’s records before you spend a dime.
The well head must sit a minimum distance from any habitable structure, and many Oak Hills parcels have wells placed too close to the planned build site. We’ve relocated a well head off Coyote Trail to satisfy the county’s 100-foot minimum, working with a civil engineer to re-perc the leach field in the process. We check the well location during the first site walk.
San Bernardino County enforces high-wind shear-wall and hold-down requirements for structures on exposed desert lots, especially east of the 15. Roof tie-downs on an Oak Hills home are not the same as a Hesperia roof two miles away. We spec the engineering to the county’s wind map and submit calcs with the permit set, so plan check doesn’t bounce us back on round one.
We start with a topographic read and the county’s drainage requirements for the parcel, then design a balanced cut-and-fill plan that keeps driveway grades under 10% where concrete trucks need access. On a recent ADU off Coyote Trail, that meant keeping a slope driveable for the pour. Drainage is scoped before we quote, not discovered after excavation starts.
Yes. We regularly step into owner-builder projects that have stalled at plan check or inspection. We take over permit management, trade coordination, and material ordering while you keep control of the design.
